Figure 4.

Measures of contiguous homozygosity surrounding outlier peak regions. Two of the top four peak regions were chosen from Table 3 for each population and
centimorgan values from the percentile extent matrix (PEmat) for the surrounding 10-Mb chromosomal area plotted as a grayscale image. Grayscale
levels are adjusted relative to the maximum centimorgan value in the 90th percentile
and values above that level set to black; correspondence between gray levels and cM
is indicated at the top of each panel. Red line: smoothed extAUC values were down-sampled before plotting. The left-hand y-axis labels refer to percentile
levels of the PEmat data, and the right-hand y-axis labels are for the line plot of extAUC values.
